Green Roof Application
Smart Green Roof System and Innovative Geocellular Storage Tank
Fully automatic irrigation
Rainwater infiltrates from the ground or enters the HOENSOEY geocellular storage tank through the drain for temporary storage. Under daily circumstances, the water in the HOENSOEY geocellular storage tank is automatically transported to the soil layer through unique water-conducting strips. Plant roots continuously absorb water from the soil, creating an irrigation-free system for plant growth. In the long run, plant irrigation no longer needs any outside interference.


Water resources storage
The ideal moisture content of the soil is promoted by the infiltration effect of passive irrigation in green roof system.
Operational budgets were reduced because water was collected on site rather than irrigated manually, which was too expensive.
The green flat roof system collects rainwater for flushing toilets, washing cars and clothes. In addition, the flat roof drainage design makes rainwater purified for drinking.
The green flat roof system helps a lot with water conservation, reducing the need for local underground water.
Excess water is pumped into the system to reduce runoff and can be easily used during dry periods. It also provides valuable water directly to plant roots, thus avoiding the waste caused by evaporation.
Low Impact Development (LID)
- The flat roof drainage design helps maintain the look and feel of natural turf without having to install an expensive system for irrigation purposes.
- Ideal for advanced lawn maintenance, landscaping and playground maintenance.
- Reduce evapotranspiration and realize optimal low impact development (LID).
- The creation of green space is maximized, and rainwater behavior is mimicked before development.
- Utilize natural and biological evaporation processes to reduce the heat island effect.
- Make rainwater useful and reduce water runoff.

HOENSOEY Cell
HOENSOEY Cell(Geocellular Storage Tank) is a new type of rainwater storage honeycomb units with ultra-high compression strength and unique buckles. They are a core component in shallow surface water treatment systems.

Green roof drainage questions & answers
How does the HOENSOEY green roof system provide irrigation?
According to the page, rainwater infiltrates from the ground or enters the HOENSOEY geocellular storage tank through drains for temporary storage, then is automatically transported to the soil layer through unique water-conducting strips, creating an irrigation-free system for plant growth.
What water-saving benefits does the green roof system provide?
The page states that the system stores rainwater on site, reduces the need for manual irrigation, lowers operational budgets, reduces dependence on local underground water, and can reuse collected water during dry periods.
Can the green roof system support low impact development (LID)?
Yes. The page explicitly says the flat roof drainage design supports low impact development by reducing evapotranspiration, maximizing green space creation, mimicking pre-development rainwater behavior, reducing heat island effects, and reducing runoff.
What role does HOENSOEY Cell play in the green roof system?
The page describes HOENSOEY Cell as a geocellular storage tank and a new type of rainwater storage honeycomb unit with ultra-high compression strength and unique buckles, serving as a core component in shallow surface water treatment systems.
How does HOENSOEY Cell compare with common drainage boards and plastic trays?
The comparison table on the page states that HOENSOEY Cells provide 95% water storage, 800 kN/m² compressive strength, self-circulation with even water distribution, better integrity, faster and safer installation, about 50 years of service life, and lower overall cost comparison than common drainage boards and plastic trays.
What products are linked from this green roof application page?
